Frequently Asked Questions
Will these bags fit a 16–17 inch laptop?
CROCOD advertises fit up to 17.3-inch laptops. MOSISO models are sized for up to 15.6-inch laptops — check your laptop's dimensions against the listed compartment sizes to be safe.
Which bag is easiest to carry through TSA?
Look for a bag with a wide top zipper or quick-access rear pocket and a stable laptop strap. The MOSISO Sage Green has structured padding and easy-access compartments that speed laptop removal; CROCOD's roomy pockets also help but the canvas design may need more unpacking.
Are these bags water-resistant for light rain?
MOSISO bags use waterproof PU leather and typically repel light rain better than canvas; CROCOD uses canvas with PU trim which is less waterproof but still durable. For heavy rain, add a rain cover or choose a fully waterproof travel bag.
